Well, I was in stop and go traffic the other day (temps were normal) but speed was right around where 1st changes into second and vice versa. I noticed that when the transmission upshifted from 1st to 2nd, it would clunk and jerk the whole vehicle. ell after a while of stop and go, i just figured it was just a quirk I need to get used to. After about 20-30 mins of this traffic, I would lightly press the gas to move up and when the transmission shifted from 1st to 2nd, it revved up, almost like it was in neutral, then chirped the tires when it caught second gear. (dealer could not replicate, and says its fine)

Not to be rude.

I'm going to make them ride in the truck with me when I do it. just so they can see.

if they say its fine, then i'm going to find a way to break it.

checked the fluid level today. cold engine, on flat surface, and the fluid level was 1/8" off being dead center. just a tiny bit lower than perfect.

My thought: the problem is that the dealer could not replicate the problem. You as the one who drives it all the time, are in a better position to know when it acts up and when it doesn't. In many ways, I would agree with the "take him on a ride" approach. Maybe start with, "I recognize this problem is intermittent, how did you test it last time? ___ Those aren't the kind of conditions/situations where I experience the problem. It only seems to act up when _____. Would it be helpful if me and your technician went out together so I can show him the symptoms and the driving situation(s) that trigger the symptoms."

I understand your frustration with the dealership not being able to duplicate an issue you are experiencing with your vehicle. I am happy to locate another dealership in your area for a second opinion. If interested, I could even set up the appointment for you. Please private message if I can be of any assistance.
